I have used Death Clock from deathclock.com, and really it just does not work. Two optimistic twins will die exactly on the same day, and if you are Sadistic it is simply cut by 1/3. I enjoyed using it, but it is just pointless as it is like a broken clock that runs backwards. Its not exactly scary or anything, as it is calculated and if you are going to die in 2040, does that mean you are going to jump in front of a speeding lorry and dive underneath the tyre?
Exactly. It really is just scrap. I have used this much more accurate death test, search for it on yahoo! if you want a go. It gives you a really long quiz of yes or no and tells you when a bit more precisely, and gives you the % chance of the cause of your death. Although it doesnt work.
Well, if you are bored out your mind, then give it a go, and be (dis)enlightened. Not reccomended, though.
